Abstract

New cobalt (II) complexes of general formula [Co(L) (NO₃) (H₂O)₂]·NO₃ (L = methyl 2-(pyridine-2yl-methylene) hydrazinecarboxylate, C₈H₉N₃O₂ (2-PYMC) (1) and ethyl 2-(pyridine-2yl-methylene) hydrazinecarboxylate, C₉H₁₁N₃O₂ (2-PYEC) (2), have been synthesized and characterized by elemental analysis, UV–vis, IR, and photoluminescence measurements. The crystal structures of 1 and 2 reveal the presence of CoN₂O₅ pentagonal-bipyramidal coordination polyhedra in each complex: the basal plane consists of an N, N, O-tridentate 2-PYMC/2-PYEC ligand and a chelating nitrate anion and the axial sites are occupied by water molecules. The crystal structures are consolidated by O–H⋯O and C–H⋯O hydrogen bonds.
